Patent number: 7909551Abstract: An apparatus and method for shaving the inside of barrels. The invention relates to reconditioning used wine barrels by shaving the inside surface to a predetermined depth, ready for re-crozering, toasting, and re-use. Conventional shaving methods typically involve routing the internal surface by hand, but this technique is problematic in that it is a very slow process, the quality of the wood is often adversely affected, and there is no way of ensuring that the surface will be shaved to the same depth across the entire surface. The resultant internal dimensions of the barrel are not reflective, relatively, of the original barrel surface. The invention includes a scanning device to scan the internal dimensions of the barrel, and a cutting device to shave the internal surface to a predetermined depth relative to the scanned internal dimensions and where the scanning device and the cutting device may be supported by different robotic arms.Type: GrantFiled: July 6, 2010Date of Patent: March 22, 2011Assignee: Southern Cross Cooperage Pty LtdInventor: Breck Waterman

Patent number: 7771146Abstract: The present invention relates to an apparatus and method for shaving the inside of barrels. In particular, the present invention relates to reconditioning used wine barrels by shaving the inside surface to a predetermined depth, ready for re-crozering, toasting, and re-use. Conventional shaving methods typically involve routing the internal surface by hand, but this technique is problematic in that it is a very slow process, the quality of the wood is often adversely affected, and there is no way of ensuring that the surface will be shaved to the same depth across the entire surface. Therefore, the resultant internal dimensions of the barrel are not reflective, relatively, of the original barrel surface. The apparatus of the present invention includes a scanning device adapted to scan the internal dimensions of the barrel, and a cutting device adapted to shave the internal surface to a predetermined depth relative to the scanned internal dimensions.Type: GrantFiled: November 14, 2008Date of Patent: August 10, 2010Assignee: Southern Cross Cooperage Pty LtdInventor: Breck Waterman

Patent number: 5110239Abstract: A vacuum clamping system for trimming a flat or gently curved part from a sheet of material includes a template and a plurality of hold-down members, or pods, that sandwich the template between the pods and the workpiece. The template has a plurality of circular openings through its thickness. Each pod has an expandable bellows with an open suction end that extends downwardly through one of such openings, and comes into contact with and is closed by the workpiece. Subsequent evacuation of the bellows causes it to contract, thus pulling the workpiece tightly against one side of the template, and further pulling a clamping portion of the pod tightly down against the template's other side. This fixes the template in position between the pod and workpiece. Preferably, a number of pods are used in combinatiton with any given template to improve the clamping action.Type: GrantFiled: April 26, 1991Date of Patent: May 5, 1992Assignee: The Boeing CompanyInventors: A.
